SAKOR designed this system for testing such driveline components as transmissions, differentials, and transfer cases. The system is specially configured so each dynamometer can run independently as a spin stand with its own DynoLAB PT controller, or both dynamometers can be controlled by one DynoLAB system to provide an integrated drive/load testing system. The dual dynamometers have been engineered with a common regenerative front end that is not only extremely power efficient but also allows the dynamometers to be completely air-cooled, eliminating the need to provide fluid-cooling capacity.
